Take care of a few stragglers and make netdev->dev_addr const.
netdev->dev_addr can be held on the address tree like any other
address now.

The future is here, convert the new driver as we are about
to make netdev->dev_addr const.

Argument comes from netdev->dev_addr directly, it needs a const.

wilc_set_mac_address() calls IO routines which don't guarantee
the pointer won't be written to. Make a copy.

Add const to the address param of ipw_send_adapter_address()
all the functions down the chain have already been changed.
Not sure how I lost this in the rebase.

Commit 406f42fa0d3c ("net-next: When a bond have a massive amount
of VLANs...") introduced a rbtree for faster Ethernet address look
up. We converted all users to make modifications via appropriate
helpers, make netdev->dev_addr const.
The update helpers need to upcast from the buffer to
struct netdev_hw_addr.

There are no module callers in-tree and it's hard to justify
why anyone would init or flush addresses of a netdev (note
the flush is more of a destructor, it frees netdev->dev_addr).

netdev->dev_addr should only be modified via helpers,
but someone may be casting off the const. Add a runtime
check to catch abuses.
